FINISHINGCASE FOR RAILWAY-BARS.

The Schedule referred to in these Letters Patent and making part of the same.

To all 10hom 'it mayconce'rn.:

` being a part of this spccilication.

Figure-1 shows mydevice open, with a rail therein.. This device I call a rail-finishing carriage.

FigureZ shows the4 device closed and in perspective.

Like letters indicate like parts in each figure.

The object of ths'ini-*ention is to construct a heavy' metallic case, in two sections suitably hinged together, whose interior shall accurately fit, and whose length shall be equal to the length of a railway-bar, and wherein the rail, which is bent when it leaves'the finishingrolls, may be received and straightened, that is, provided with sui-table channels, through which water or other suitable cooling-fluids may be brought to act upon the head ofthe rail, while hot, thereby hardening said head; wherein the rail may be presented to the saws usually employed to cut olf the ends, and suitable punches may be brought into action, to punch/the boltholes through the web ot' the rail, by means of which Ilroles and proper bolts, fish-plates may be, when desired,

secured tothe rail, proper holes through the top ofl the hea' or case acting as guides to the punches, and whereifn the rail will be so tightly clasped that its ends may he made more dense and compact, by being upset `by blows upon its ends, without the shape or s ize of the ,rail being altered thereby, the whole forming a valuable adjunct to every rail-mill, and enabling the operators to do away with the straightening-press, and its slow and imperfect operation, to harden the head of therail without affecting the foot or web, to allow the latter to be punched while being straightened, and the ends to be hammered to increase their hardness, without the necessity of so frequent handling and so much manipulation as is now required in iinishing a railand strong not to spring in any direction when in operation.

The-interior should be made in each section to fit one side ofthe rail, so that when closed, it will closely t and clasp the rail upon all sides.

The rail, as it comes from the finishing-rolls, is hot, and generally warped'and twisted. The case being open, and ready to receive the rail, it is placed therein, and the box closed.v y

Any'suitable fastening, a, may be employed to-hold the two sections of the case in position when closed, and the fastenings may be such as will compel the upper section to close o'n the lower, when the twist of the lrail prevents this from being readily done.

The lower side of the case being fitted with proper wheelsfand the rail being inclosed in the case, the whole is presented to the saws, which cut oi the ends of therail which project from the ends of the case','so that the 'rail will be left the desired lengt-h.

B are holes, which pass through the case in a vertical direction, of the proper size to act as guides to suitable ,punches b, with which the fish-plate boltholes are punched in the web orneck of the rail.

-The punches may be operated by any convenient device, and should lbe used while the rail is hot.-

C are openings in the end of the sections, which connect with channels al, through which water may be admitted to contact with the head, thereby cooling it, and hardening said head when'desired.

D are other openings in the side of the case, which also connect with the channels d, and through which water may be admitted when more convenient.

lThecase .accurately and closely grasping the rail, if' it is desired to hammer the ends thereof, to make them harder and less liable to lamination, the ends may be hammered, without any danger ot' changing the form and size of the rail.

What I claim as myinvention, and desire to secure by Letters Patent, is-

'lhe case or finishing-carriage A, constructed as de- 4 scribed, 'whereby railway-bars may be straightened, punched, sawn olf, upset, hammered, cooled, and hardened while in said case, substantially as herein set forth.

JOHN BURT.
